Hey everyone. I'm in HS stats class, literally right now. And I've got this project to do, and I want to do it on backpacking light, why not, right?
The topic is completely up to me, I've been assigned to gather data and then statistically find out if there is a correlation between two things.
Some projects my classmates testing:
is there a correlation between professional athlete steroid use and injuries?, do sports teams with best stats go to the playoffs?, does the market value of a city reflect on the stats of the nba team?, et cetera et cetera.
Any ideas? Any gear makers or staffers have anything they would like to test but aren't sure exactly how to test it? I know how! No idea is too big or too small, I mean at least to brainstorm.
Ideally the information would already be out there, and I would only have to gather it. But maybe a survey isn't too far fetched. Anything is possible. I have about 1 month before this project is due, and I need a topic idea ASAP!!
so, go!May 7, 2010 at 2:49 pm #1607516
i have no thought or suggestion to contribute. however, great idea and good luck with the project.May 7, 2010 at 4:01 pm #1607542
o man, i remember my high school stats project…it paled in comparison to what you're proposing
Off the top of my head…is there a correlation between:
Income/Job type vs Number of nights spent outdoors in a year
Body Mass Index vs. Avg Baseweight (might not get anything, since most everyone has a lightweight baseweight on this forum)
Number of Packs owned vs. Number of divorces :) (this one is a joke)
Either way, just setup an anonymous survey (theres survey sites out there that can do this i think) or have people personally PM you.
I see if I can think of some more later
Let us know your findings!May 7, 2010 at 4:08 pm #1607544
I would like to know this. I see a lot of people tell you to throw out an expensive piece of gear in favor of a more expensive, but one ounce lighter, piece of gear. I have a limited budget to work with and sometimes you just can't toss items like that. My question is; Can a person with a set amount of money enjoy light backpacking? How much money do you spend for; (base weight) 20 pounds, 15 pounds, 10 pounds, 5 pounds? (spring or fall weather)May 7, 2010 at 4:13 pm #1607546
Is there a correlation between:
Education level and BPL membership
Those interested in both hunting and lightweight hiking and where they live
Cottage gear manufacturers base of operations and hiking opportunities in the area
The amount of gear BPL members buy in a month and the number of posts Ben Tang makes in that month
Pack base weight and body weight
Those are a few to get you started!May 7, 2010 at 4:17 pm #1607548
hahahah to amt of gear and Ben's posts
…thats 2 for Pack base weight and BMI/body weight
Please, i need to know if I was overcompensating for something else when I use to haul around that 45lb packMay 7, 2010 at 5:34 pm #1607572

Chris, that is why there is one forum section in here for Make Your Own Gear.
Now, I recognize that many of us do not have all of the skills to make our own down sleeping bag or other big-ticket item as perfect as the one that we purchase. However, lots of the little items can be made at home. For example, coke can stove and alcohol stoves in general. Lots of stuff can be rescued at a dollar store or a Goodwill store. Try it.

Pack weight and number of miles hiked in a day. It'd be nice to know that vs. anecdotal charts that are out there.May 7, 2010 at 7:41 pm #1607625
"Can a person with a set amount of money enjoy light backpacking?"
This thread addresses that topic.
I haven't read it in a while, but someone in there shopped WalMart and Salvation army, Knew his stuff, and did Very well, for Very little. As long as you aren't aiming for the "Outside" look, and can suffer the indignity of using a "Grease Pot" instead of titanium, you can do OK.

In the early 80's I discovered that each additional pound on my back reduced my maximum distance traveled by about one mile per day. Ignoring the fact that I got stronger as I went and that my pack got lighter, I once decided to calculate what the maximum distance I could travel unsupported might be.
Here's how (I was just a college student, so not too sophisticated): without anything I could make a 60 mile day pretty reasonably, if painfully (did it on the Kenai Peninsula trails). However, for each day of travel I carried an additional one pound for food. Assuming all my gear weight was fixed at, say, 15 pounds for a camping trip and I was going for X days then my pack would way 15 + X pounds = gear weight plus X days worth of food (pretty light on food but not bad for shorter trips 1 month).
So my total distance traveled in one day would be
60 miles minus 15 miles for the gear weight minus X miles for the food weight
= 60 -15 – X = 45 – X.
Now the question is how far can I go at a maximum on a multi-day trip where I keep adding weight for more days of travel?
So, I'll go for X days at 45 – X miles per day making the total trip length as number of days times miles per day =
total trip length = X (45-X).
I can go nowhere in no time (X = 0 days) or nowhere with a pack too heavy (X = 45 days worth of food; of course not true, but bear with me), but for some in between X I'll maximize my total distance.
Interestingly, the maximum distance I could go (using the formula) would be 506 miles in x= 22.5 days, which is not too far off Coup's CT record of 420 miles in 20 days.May 7, 2010 at 9:28 pm #1607660
I'd try to snag the data set from the tarp survey that went down last month. Secondary analysis is always easier!
The problem with some of the above ideas is that you'll need enough of a sample to have something approaching a control.May 7, 2010 at 9:54 pm #1607672

Now, now David… Are you suggesting that the man steal his data rather than conduct a small survey of his own?… If so… Tisk, tisk.
Why not conduct a small survey of your own, once you come up with a thesis, right here on BPL? There must be hundreds of correlations you could make right here on BPL. I'm sure if you posted your query in the, "Chafe" forum MANY members would give you exactly what you need.May 8, 2010 at 4:00 am #1607712

One individual is not enough of a sample to make a correlation. I suspect (but haven't tested) that pack weight and miles hiked are correlated but not as strong as a formula would lead one to believe.May 8, 2010 at 4:48 am #1607713

Search for Ryan Jordan's discussion of the Arctic 1000 trip. This is discussed in the context of how much food to carry.

"Now, now David… Are you suggesting that the man steal his data rather than conduct a small survey of his own?… If so… Tisk, tisk."
Steal, no. Using a pre-existing data set with permission, why not? Much of the most influential and interesting work in the sciences and social sciences has been done in such a manner. A month is not a huge amount of time to design, implement, and analyze a survey that addresses sample size, reliability, and validity issues.May 8, 2010 at 12:03 pm #1607794
Wow! This sure got a lot of great, quick responses. Thanks everybody.
Konrad: First, yes this is a giant project, but were doing absolutely nothing in the class other than this for the rest of the year. I especially like your 2 ideas about:
a) Income/job type VS. number of nights spent outdoors in a year.
b) BMI VS. average baseweight.
And as you said, this site is mostly full of folks with lightweight backpacks, so I'd have to find some way to collect unskewed data. Or find a way to collect enough data so that there is no skew. Perhaps there's a sister site, Backpacking Heavy?
Doug: I like your ideas, too. Especially:
c) Those interested in both hunting and lightweight hiking VS. where they live.
d) Cottage gear manufacturers base of operations VS. hiking opportunities in the area.
e) The amount of gear BPL members buy in a month VS. the number of posts Ben Tang makes in that month.
And the best thing about E is that there's already UNIMAGINABLE amounts of data. hahaha
George: I'm a little lost, what exactly are you purposing I should test? Oh wait… I like the idea:
f) Pack weight VS. daily mileage average
Roy: And you're exactly right, but who knows? None of these ideas have been tested, right? At least not to our knowledge.
And stealing? Nahhhh. My teacher recommends that I find pre-existing data, but he is very open to helping me conduct a survey. He knows I'm ambitious and he would help me accomplish whatever I choose. I'm open to either way, so long as a survey is feasible for the topic. A good thing about doing a survey is that I would be absolutely sure that my findings would be on an original topic.
Comments on ideas listed above? If I had to choose favorites I'd say:
D, F, A, B; in that order.May 8, 2010 at 11:12 pm #1607925
Ben, surveymonkey.com is a great, easy tool. 10 questions or less and it's free.
Option D seems very feasible. Large enough in scope to mean something, small enough to get specific results quickly.May 9, 2010 at 7:25 am #1607968
@figsterLocale: Central Arkansas
D for Doh! How many cottage manufacturers are there? A dozen? There aren't any within a thousand miles of me. We've lots of great trail in Arkansas, we just don't have gear hounds enough to support an awesome seamster.
Seems like stronger things can be browsed. I have no good suggestions, though.
JackMay 9, 2010 at 11:44 am #1608036
David and Jack, both great points.
David: Thank you for the website reference.
Jack: You're right, there are not very many on the subject of lightweight backpacking gear. However, I'll never know unless I try.
Tomorrow, I am going to begin to pursue D with my teacher, see what he thinks. I know it is a small survey base, but it represents a big scale, as David(?) mentioned. And I know there are threads on this site dedicated to listed cottage gear manufacturers. Can anybody help me with a citation?
But of course, no plan is complete without a backup plan. So I can't close options, and it's not to late to blow my mind with new options. Thoughts?
ps. thank you to everyoneMay 9, 2010 at 3:32 pm #1608088
Too bad you were too late to correlate the sofa accidents reported on by Ben in Chaff forum.May 9, 2010 at 5:03 pm #1608126

Does base of operations for a cottage gear maker really matter now that we have the Internet?
As for "backpacking heavy" sister site, try backpacker.com.
On the subject of going light and cheap, I just posted pictures of all my gear and if you look at it closely, you'll see that much of it is salvaged junk, make your own and thrift-store stuff. My BMI is a little above optimum, too.May 12, 2010 at 2:42 pm #1609189
correllation between count of giardia in lakes frequented by backpackers, stock, swum in by backpackers, and never visited by either stock or backpackers. I have seen reports on this topic, on the web.
